Installation by Alexandre Mulongo Finkelstein and Livia Cahn

Brussels is partly built on sand (SiO2, silicon dioxide). This sand was probably deposited by a tropical sea or a delta. In the Middle Ages, sand was extracted from the subsurface of Saint-Gilles, near the rue du fort. The sand was used for construction works and to level the ground. The expansion of the city, put a stop to this extraction at the end of the 19th century.

Bringing sand into the vertical plane of the shop window is an invitation to ask questions about the history and the composition of the underlying underground that typically lies underfoot and out of sight. The speculative archival document in the window is mineral.
